Abstract: A controller mechanism having a selectable actuator with a touchscreen that displays a plurality of selectable options and is configured to highlight a selection from the plurality of selectable options by touch, and extending outward from the actuator is a plurality of protrusions; a frame having an aperture through which the selectable actuator extends and the plurality of protrusions do not extend; a carriage having a spring that presses against the selectable actuator at a plurality of different locations to float the plurality of protrusions against the frame and a shared selection button that can be pressed by the actuator when the spring is compressed; wherein entering the selection from the plurality of selectable options includes highlighting the selection by touch and pressing the selection button; and wherein the plurality of protrusions prevent substantial lateral movement of the actuator.
